Help! Can I do HIIT raining and tone up/gain muscle?
Hi, I've been doing high-intensity interval running on the treadmill (toggling back and forth between speed 8.0 and 6.0; afraid to run outside because it's always raining where I live unfortunately).... I was wondering - is there a way for me to gain muscle mass and tone up this way without losing weight? I'm light and weight loss is not a concern of mine. But unfortunately, I hate lifting weights.
Should I do HIIT running and then supplement lots with protein/carbs?
